DESCRIPTION

Referring to the drawings, a vehicle spare tire carrier according to the teachings of the present invention is shown and generally indicated as 10. Generally, carrier 10 stores and transports a vehicle spare tire 12 for a motor vehicle 14. Vehicle 14 includes a superstructure or frame 16 to which a vehicle bumper 18 is attached. Vehicle 14 further includes vehicle body 20. Body 20 includes a closure member, door, tailgate, or endgate 22 which is pivotal from a closed position to an open position about a pivot axis 24. In the preferred embodiment, pivot axis 24 is horizontal such that tailgate 22 is pivotal from a vertical closed position to a horizontal open position.

Carrier 10 includes a first, lower arm 26 having a first end 28 and second end 30. Arm 26 is elongated, in the preferred embodiment, has a length which is less than the diameter of tire 12, and has a U-shaped cross section. Arm 26 further includes provisions for mounting tire 12 thereto. In the preferred embodiment, a tire mounting bracket 32 is attached thereto by bolts 34. Bracket 32 includes a first leg 36 which extends generally perpendicular to arm 26, a second leg 38 which extends generally perpendicular from leg 36 and parallel to arm 26, and a third leg 39 which extends angularly from leg 38 and arm 26. Thus, when arm 26 is in a vertical position, leg 36 acts as a shelf in positioning tire 12 for attachment to bracket 32. In the preferred embodiment, tire 12 is attached to bracket 32 by a bolt 40 which extends through an abutting member 42 which abuts with the rim of tire 12. A hook member 44 can further be provided for holding tire 12 on bracket 32 while bolt 40 is being positioned and fastened.

Carrier 10 further includes provisions for pivoting arm 26 with tailgate 22 which, in the preferred embodiment, is shown in the form of a lower pivot member 48 pivotally attached to end 28 of arm 26 and attached to vehicle 14 along with a second, upper arm 50 pivotally attached to end 30 of arm 26 and to tailgate 22.

In the preferred embodiment, arm 50 is elongated but has a length shorter than the length of arm 26 and has a U-shaped cross section. Arm 50 includes a first end 52 pivotally attached to end 30 of arm 26 about a pivot member which forms axis 54 which is parallel to axis 24. For pivotally mounting second end 56 of arm 50 to tailgate 22, an upper pivot member 58 is provided, attached to tailgate 22, and pivotally attached to end 56 of arm 50 about a further pivot member which forms axis 60. Axis 60 is parallel to axis 24 and 54. In the preferred embodiment, upper pivot member 58 has a U-shape.

Lower pivot member 48 includes a first generally flat member 62 and a second generally U-shaped member 64 extending generally perpendicular thereto. Member 64 includes a generally flat section 66 having legs 68 extending from the opposite sides thereof. Lower pivot member 48 is arranged, in the preferred embodiment, to be attached to vehicle frame 16, and in the preferred embodiment, is attached to bumper 18 by bolts 70 which extend through member 62 and section 66 of member 48.

Legs 68 of member 48 include a first abutting surface 72, best shown in FIG. 4, which extends parallel to member 62 and which is generally parallel to tailgate 22 in its open position. A second abutting surface 74, also shown in FIG. 4, extends at an angle slightly less than 90° from surface 72 and generally parallel to tailgate 22 in its closed position.

End 28 of arm 26 is pivotally attached to member 48 by a pivot member which forms axis 76 which extends through legs 68 of member 48 and arm 26. Axis 76 is parallel to axes 24, 54, and 60. A torsion spring 78 biases arm 26 with respect to member 48.

In use, when tire carrier 10 is in its first position as shown in solid lines in FIG. 3, tire 12 can be attached to or removed from bracket 32 in a manner similar to conventional tire carriers. In operation, in the first position of carrier 10, arms 26 and 50 are generally in line, or in other words, generally parallel to each other, with arm 50 extending from second end 30 of arm 26. If it is desired to open closure 22, closure 22 is simply opened and pivoted from its first closed position to its second open position as if carrier 10 were not located on vehicle 14 or attached to closure 22. Thus, as closure 22 pivots about axis 24, arms 26 and 50 similarly pivot about axes 54, 60, and 76 to its second position as shown in phantom in FIG. 3. Thus, arms 26 and 50 pivot in relation to each other, or in other words, fold from their first generally straight position to their second angular or folded position. In the preferred embodiment, arms 26 and 50 are approximately at a 50° angle in the second position of carrier 10.

In its second position, arm 50 is at an angle to arm 26 and in the preferred embodiment, does not extend generally beyond second end 30 of arm 26. Specifically, due to the length of arm 26, tire 12 extends beyond second end 30 of arm 26 such that tire 12 prevents someone from accidentally bumping into pivotal ends 30 and 52 of arms 26 and 50, respectively. Additionally, due to the lengths of arms 26 and 50 in the preferred embodiment of the present invention, in its second position, pivotal ends 30 and 52 of arms 26 and 50, respectively, extend equidistant with closure 22 or in other words to a point generally vertically below the end of closure 22 and thus do not obstructively protrude beyond closure 22 and thus present an obstruction. point to passers-by even when tire 12 is removed from carrier 10.

Thus, it can be appreciated that the respective and comparative lengths of arms 26 and 59 of the preferred embodiment of the present invention allow an overcenter type of mounting of arms 26 and 50 as described and provides several advantages, some of which are set forth hereinbefore.

Prior to the present invention, known spare tire carriers are considered to have had serious shortcomings. For example, many tire carriers were attached to and supported by vehicle body 20 rather than frame 16 or bumper 18. Therefore, it was necessary to reinforce body 20 at the attachment locations which often required removal and replacement of the vehicle interior, and thus was very time consuming. Further, due to bouncing and jars as vehicle 14 travelled along a roadbed, prior art carriers would often pull away from body 20, thus damaging body 20.

Further, many known prior tire carriers required that the tire carrier be pivoted out of the way and separately from closure 22 before closure 22 could be opened. Thus, a two step procedure was necessary, first to unlatched and pivot the tire carrier and second to unlatch and pivot closure 22. Thus, these known prior tire carriers do not work simultaneously with closure 22, as does the present invention, but must be operated separately. This is not very handy and is a time comsuming procedure.

Additionally, many known prior tire carriers prevented operation of the vehicle with closure 22 in its open position because the tire carrier could not be secured with closure 22 in its position.

The present invention solves these and other problems of the prior art. Specifically, carrier 10 according to the teachings of the present invention operates simultaneously with closure 22. Specifically, closure 22 can be opened and closed as if carrier 10 were not connected to vehicle 14. Carrier 10 pivots simultaneously with closure 22 in a single procedure. Thus, the two step procedure of the prior art is not required.

Further, in the preferred embodiment, spring 78 can be arranged to compensate for the added pivotal load on closure 22 and permit closure 22 to open and close as if carrier 10 were not mounted thereon. Additionally, spring 78 can be arranged as a two position torsion spring such that carrier 10 will not hold closure 22 in a position between its open and closed position when tire 12 is removed from carrier 10.

Further, carrier 10 of the present invention, in its most preferred mode, transfers all weight of carrier 10 and the spare tire mounted thereto to frame 16 of vehicle 14, and thus, carrier 10 is carried by frame 16 of vehicle 14 rather than vehicle body 20. Specifically, lower pivot member 48 receives all the weight of carrier 10 which transfers the weight to bumper 18 which in turn transfers the weight to frame 16. Additionally, due to the construction of pivot member 48 of the preferred embodiment of the present invention and specifically due to the overcenter pivoting arrangement of arm 26 with pivot member 48 at pivot axis 76, when carrier 10 is in its lowered position, inside surface 73 of arm 26 abuts with surface 72 and thus acts as a stop for carrier 10 to prevent arm 26 from pivoting therebeyond. Thus, when closure 22 is in its open position, the weight of carrier 10 is carried by pivot member 48 through arm 26 and surfaces 72 and 73 and thus carrier 10 does not place any weight on closure 22 and eliminates unnecessary forces and stress on closure 22. Further, it can then be appreciated that vehicle 14 can be operated with carrier 10 and closure 22 in its open position.

In its raised or transport position when closure 22 is in its closed position, the weight of carrier 10 is transferred to pivot member 48 by inside surface 73 of arm 26 abutting with surface 74. In the preferred embodiment of the present invention with surface 74 being at an angle slightly less than 90° , or in other words surface 74 is at a slight angle to the vertical, the weight transfer at surface 74 is enhanced. Thus, surface 74 stops any further movement of arm 26 therebeyond and further eliminates unnecessary forces and stresses on closure 22.

Now that the basic teachings of the present invention have been explained, many extensions and variations will be obvious to one having ordinary skill in the art. For example, although carrier 10 is especially adapted for and preferred for use with vehicles having closures which pivot about a horizontal axis, carriers 10 utilizing the teachings of the present invention could be constructed for vehicles having closures which pivot about a vertical axis.

Likewise, in an alternate embodiment of the present invention as best seen in FIGS. 5-7, carrier 10' includes a torsion bar or rod 80 for biasing arm 26 with respect to member 48 and thus with respect to vehicle 14. Specifically, torsion bar 80 includes an elongated central portion 82, a first leg 84 attached to the first end 85 of portion 82, and a second leg 86 attached to the second end 87 of portion 82. In its most preferred form, legs 84 and 86 are generally perpendicular to portion 82. Leg 86 in its most preferred form includes a leg portion 88 attached thereto and in its most preferred form attached generally perpendicular to leg 86 and generally parallel to portion 82 but extending beyond second end 87 of portion 82.

Torsion bar 80 is mounted to frame 16 of vehicle 14 such that leg 84 abuts with a portion of frame 16 or other portion of vehicle 14, central portion 82 is free to twist or rotate, and with leg portion 88 being located adjacent arm 26 and free to rotate about an axis defined by central portion 82. In its preferred form, bar 80 is mounted by U-shaped clips 89 attached to frame 16 and through which central portion 82 of bar 80 extend. In its most preferred form, clip 89 adjacent end 85 of bar 80 is mounted to the portion of frame 16 attached to bumper 18 and clip 89 adjacent end 87 of bar 80 is mounted to a support bracket interconnected between the portion of frame 16 supporting the fuel tank of vehicle 14 and bumper 18. Thus, first leg 84 acts as an anchor for preventing first end 85 of central portion 82 of torsion bar 80 from rotating. Second leg 86 acts as a lever or crank arm for placing a twisting or torsional force on the second end 87 of central portion 82 of torsion bar 80.

Carrier 10' further includes an ear 90 formed on arm 26 adjacent first end 28. A turnbuckle assembly 92 is further provided having a first end 94 for pivotal connection to leg portion 88 and having a second end 96 for pivotal connection to ear 90. Turnbuckle assembly 92 has a variable length to take up mounting and manufacturing tolerances and to allow variations in weights of spare tire 12.

To assist or replace surfaces 72 and 73 in performing the function of preventing arm 26 from pivoting below a generally horizontal position and transferring the weight of carrier 10' to vehicle 14, carrier 10' includes a cable stop 98 having a first end 100 attached to arm 26 and second end 102 attached to pivot number 48. Thus, as best seen in FIG. 6, when carrier 10' is in second position, cable stop 98 is tight between member 48 and arm 26 and thus prevents further pivoting of arm 26 beyond its second position.

In its most preferred form, the plane of leg 84 and the plane of leg 86 and leg portion 88 are at an angle to each other. Thus, carrier 10' is biased in either its first and second position and will not move from either position, without additional force. Specifically, with assembly 92 attached between ear 90 of arm 28 and torsion bar 80, to move carrier 10' from its first position to its second position requires that leg portion 88 be pivoted about central portion 82. However, since leg 84 abuts with frame 16, a torsional force must be placed on central portion 82. Thus, a sufficient force such as the force of the operator opening closure 22, must be placed on carrier 10' to overcome this torsional force.

It can be appreciated that arm 50 attached to closure 22 and second end 30 of arm 26 holds arm 26 in its vertical position since closure 22 is locked in position. Further, it can be appreciated that the overcenter pivoting arrangement of arms 26 and pivot member 48 at pivot axis 76 and the abutting surface 73 of arm 26 with surface 72 transfers generally all weight of carrier 10' and spare tire 12 mounted thereon to bumper 18 rather than closure 22 even though jars, bumps, and other movement is made on carrier 10' as vehicle 14 travels on the road surface.

Likewise, when arm 26 and carrier 10' is moved between its first position and its second position, a torsional force is placed on central position 82 of torsion bar 80. This torsional force counteracts with the force of gravity placed on tire 12 and carrier 10' and allows the gradual pivoting of arm 26 from either its vertical position to its horizontal position or from its second, horizontal position to its first, vertical position. Thus, in the alternate embodiment of FIGS 5-7, torsion bar 80 compensates for the added pivotal load on closure 22 and permits closure 22 to be opened and closed as if carrier 10' were not mounted thereon. It can then be appreciated that torsion bar 80 insures that undue weight or stress is not placed on closure 22 as closure 22 is pivoted between its first and second positions in addition to reducing the effort required in pivoting carrier 10' with closure 22. Additionally, it should be noted that torsional force of torsion bar 80 is not sufficient by itself to move the mass of carrier 10' and closure 22 from its open to closed position, even if spare tire 12 is removed from carrier 10'.

It can then be appreciated that the use of torsion bar 80 according to the teachings of the alternate embodiment ofthe present invention rather than the torsion spring 76 of the first described embodiment of the present invention provides several advantages including the ability to better compensate for the added pivotal load on closure 22. Furthermore, torsion bar 80 can be utilized with other methods and constructions for holding arm 26 in its vertical position during transport, whether or not arm 26 is pivotal simultaneously with vehicle closure 22.

Thus, since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or the general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive.
